“…The as-cast alloy morphology has some plate-like structure and evidence of formation of an intermetallic-like phase within the matrix of the alloy ( Figure 5). This plate-like structure has been identified as aluminium-titanium intermetallics with transmission electron microscope [7] while the precipitate-like phase represents TiB 2 [8]. Previous work has shown that TiB 2 reinforcement is both thermodynamically and microstructurally stable within the aluminide matrices [9].…”

This paper examines the effects of heat treatment processes on the mechanical properties of as-cast Al-4% Ti alloy for structural applications. Heat treatment processes, namely, annealing, normalizing, quenching, and tempering, are carried out on the alloy samples. The mechanical tests of the heat treated samples are carried out and the results obtained are related to their optical microscopy morphologies. The results show that the heat treatment processes have no significant effect on the tensile strength of the as-cast Al-4% Ti alloy but produce significant effect on the rigidity and strain characteristic of the alloy. With respect to the strain characteristics, significant improvement in the ductility of the samples is recorded in the tempered sample. Thus, for application requiring strength and ductility such as in aerospace industries, this tempered heat treated alloy could be used. In addition, the quenched sample shows significant improvement in hardness.

“…A comparison of mechanical properties of unreinforced Al 6061 alloy and Al 6061/12 wt% Titanium Diboride (TiB2) MMCs manufactured through in-situ process was made. Result revealed that mechanical properties of MMCs were higher than unreinforced alloy [4].The tensile strength of Al/5 Vol. % of Silicon Carbide (SiC) composite fabricated by stir casting route was found high than the same composite fabricated by powder metallurgy technique [5].…”

“…An attempt was made to synthesize the in-situ composite withA356 as matrix material and TiB 2 as the reinforcement eliminating the inherent associated defects with exsitu process like agglomeration, poor wettability and nonuniformity of distribution. The as-cast aluminium based reinforced composites requires to be heat treated for enhancing its mechanical properties (5).Nevertheless, the synergic impact of heat treatment and the kind of reinforcement plays a huge part in dictating the final mechanical properties of composites (6). The microstructure was used to confirm the size and uniformity of TiB 2 particles.…”

:In this work, A356 cast aluminium alloy with 6% TiB 2 in-situ formed MMCs have been fabricated using stir casting route and poured at sand and permanent moulds. The composite was synthesized using stir casting technique. The A356 cast aluminium alloy and all synthesized composites are subjected to solutionizing treatment at a temperature of 540˚C for one hour, followed by quenching in hot water at 43˚C. The quenched samples are then subjected to artificial aging at 171˚C for 8 hours. Morphology of the cast composites was studied in detail by the optical microstructure. The Mechanical properties have been carried over on both sand and permanent of Al/TiB 2 MMC composites before and after heat treatment. Under heat treated condition, Al/TiB2 composites showed better tensile strength and hardness when contrasted with base Al matrix alloy. And different moulds were investigated and its comparison shows that the tensile and hardness value of Al/TiB 2 MMC is higher than permanent mould.
